"should I just keep quiet because i find boredom and injury comes with single sport focus?"
No, I'm not trying to come across in that manner at all. Saying you get bored and could injure yourself with a single sport focus is a lot different than stating you think biking is a benefit to finishing the marathon because it allows you to train aerobically for more than 3 hours. So again, your relative success at marathon running comes from your marathon training, not your biking. If you don't think this is true, then so be it.
